What would be better for gaming>

Well, the 8700GT in the Satellite is more powerful than the 3650, but the CPU is also weaker in that system. I'm not sure if the CPU in the Asus would be able to boost it's performance to the level of the Satellite. I think I would place my bet on the Satellite as being the better performer in games.
 
The CPU isn't that big of a factor when gaming... I think the Toshiba would still crank out more FPS. Go with the Toshiba... CPUs are upgradeable, GFX cards are usually not.
 
Age of Conan needs a very good GPU (GeForce 7900 GTX recommended). Are you sure you want a laptop to play games like this?
 


I think it will do great while he's not using Dx10 in games or the higher settings with AA on.
 
Better reviews on the Asus one... I'd probably go with that one for that reason and for the fact that it's asus vs toshiba... but that's just my personal preference coming through.
